Answer:

The roots are -5, 1.

Step-by-step explanation:

f(x) = x^2 + 4x - 5

The roots of a function are also the Ox intercepts, so basically we're finding when is the function equal to '0'.

x^2 + 4x - 5 = 0\\(x-1)(x+5) = 0\\x_1 = 1, x_2 = -5

A person carries 3 bottles of compound X, 3 bottles of compound Y and 3 bottles of compound Z. While X and Y will react vigorous
Inessa05 [86]

Answer:  The number of permutations taken 3 at a time would be

  9! / (3! * 3! * 3!) = 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 / (6 * 6 * 6)

= (9 * 8 * 7  * 5 * 4 * 1)  / 6 = 8 * 7 * 5 * 6 = 1680

Example:  (1 , 2 , 2 ) = 1, 2, 2    2, 1, 2 and 2, 2, 1   3! / 2! = 3

because the 2's are indistinguishable

Now you can put these into groups of 3 and for no reaction all

of the Z bottles must be in 1 group or else a reaction will occur

The number of combinations taken 3 at a time will be

C (9 , 3) = 9! / (3! * 6!) = 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 / (3! * 6)

9 * 8 * 7 / 3! = 12 * 7 = 84    groups taken 3 at a time where all of the Z

bottles are in 1 group.

Then the probability of no reaction is 84 / 1680 = .05

and the probability of a reaction is .95
